When white light passes through a glass prism, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, and it occurs because the speed of light changes when it travels through different substances.
The phenomenon of refraction causes different colors of light to bend at different angles when passing through a prism. This is due to the fact that each color of light has a different wavelength, and the speed of light is dependent on the wavelength.
The dispersion of white light into its constituent colors is the result of the phenomenon of refraction. When white light enters a prism, it is split into its component colors, forming a spectrum. The colors of the spectrum include red, orange, yellow, green, blue, indigo, and violet.
Now, let's understand why the correct answer is option 'D' - "violet colored ray undergoes maximum deviation."
1. Refraction of Light:
When light enters a glass prism, it undergoes refraction twice - once when it enters the prism and again when it exits the prism. The refraction occurs because the speed of light changes as it enters and exits the prism.
2. Dispersion of Light:
Due to the phenomenon of refraction, each color of light bends at a different angle when passing through the prism. This causes the white light to spread out into its constituent colors, forming a spectrum.
3. Deviation of Light:
The deviation of light refers to the change in direction of light as it passes through a prism. The amount of deviation depends on the wavelength of light, with shorter wavelengths being bent more than longer wavelengths.
4. Violet Light:
Violet light has the shortest wavelength among the colors of the spectrum. As a result, it experiences the maximum deviation when passing through a prism. This means that violet light bends the most when compared to other colors.
5. Other Colors:
The other colors of the spectrum, such as red, orange, yellow, green, blue, and indigo, also undergo deviation when passing through a prism. However, their deviation angles are less than that of violet light.
Therefore, the correct answer is option 'D' - "violet colored ray undergoes maximum deviation" because violet light has the shortest wavelength and experiences the most bending or deviation when passing through a glass prism.
